list_updates

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description only states it lists recent updates. No behavioral traits are disclosed beyond the basic operation. With no annotations provided, the description should convey more (e.g., whether it is read-only, if authentication is needed), but it fails to do so.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that conveys the basic purpose. It is appropriately brief, though it could be expanded slightly to add value without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simple tool with no output schema and no annotations, the description is minimal but fails to specify what the output contains, ordering, or other details that would help the agent use the result. It is incomplete for a well-rounded definition.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage for the single parameter 'limit', which is well-documented as 'Número máximo de actualizaciones a mostrar'. The description adds no additional meaning beyond the schema, aligning with the baseline 3 for high coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Lista las actualizaciones recientes' indicates listing recent updates, but 'updates' is vague and does not specify what kind of updates (e.g., system updates, resource updates). It does not distinguish from sibling list tools like list_alerters or list_builds, which target specific resources.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. There is no mention of context, prerequisites, or exclusions, leaving the agent without direction on appropriate usage scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
